Latest Patents
Among his latest patents, Crossman has developed innovative hydraulic brake actuators and related methods. One example of his hydraulic brake actuator includes a rotary valve disposed in a bore of a housing. The rotary valve features a shaft that is rotatably positioned within a sleeve. The sleeve and the shaft are designed with ports that align at specific rotational positions, creating a flow path between the bore and an inner chamber of the shaft. Additionally, this hydraulic brake actuator incorporates a pump that is coupled to the shaft, allowing for the increase and decrease of pressure within the inner chamber.
Another significant patent involves hydraulic brake apparatus and related methods. This apparatus includes a parking brake valve that has an inlet fluidly connected to a pump and an outlet fluidly linked to a brake. The parking brake valve can operate between an open state and a closed state, enabling or blocking fluid flow through the valve. To secure the fluid in the brake during parking mode, the valve is transitioned to the closed state by pumping fluid into the inlet.
